Preliminary Engineering, Final Design, Services During Construction and Miscellaneous Services for Unforeseen Work for the 28th Street Bridge Project

Preliminary Engineering Services for the 28th Street Bridge project. The bridge carries 28th Street over two lanes of Sassafras Way, the Port Authority East Busway, and Norfolk Southern Railroad (NSRR) tracks and connects Liberty Avenue to Brereton Street (Polish Hill). Because the existing bridge is NHRP eligible, a Historic Bridge Rehabilitation Analysis will be required in addition to a Purpose and Needs statement to consider anticipated multimodal usage. Depending on the findings of the Historic Bridge Rehabilitation Analysis, the scope of work will proceed for a rehabilitation or a replacement project. For a rehabilitation option, it is anticipated that the limits of work will extend from approach slab to approach slab (inclusive) with minor changes to the horizontal and vertical alignments, as needed. For a replacement option, the scope of work will include a task for alignment investigation in order to provide alternatives for improving the approach geometry at the north end of the structure as well as reducing the structure span length and considering anticipated usage, including bicyclist and pedestrians. The alignment investigation should provide vertical alignment that provides the minimum vertical clearance requirement for a railroad crossing. Scope of Work includes, but is not limited to: project management, schedule monitoring, pedestrian and bike traffic data collection, in-depth bridge inspection, constructability reviews, coordination of public involvement, public meeting/public officials meeting, environmental documentation, Purpose & Needs, Alternatives analysis and development to meet the project Purpose and Needs, Phase I Environmental Site Assessment, Resolution of Adverse Effects, inspection for asbestos containing materials, level 2 or Level 1B CE, programmatic Section 4(f) evaluations, field surveys, research background drawings/information, research of required permits, right-of-way investigation and preliminary plans, coordination with utilities, Norfolk Southern and PUC and Port Authority, preliminary geotechnical reconnaissance, TS&L submission, preliminary lighting design, preliminary E&S plans, preliminary drainage design, preliminary maintenance and protection of traffic plan, and preliminary signing and pavement marking plan Final Design for the 28th Street Bridge project. Final Design work includes developing preliminary designs approved in the Preliminary Engineering phase and preparation of a complete construction bid package. Consultant team responsibilities may include, but are not limited to: project management, scheduling monitoring, meeting attendance, public outreach, final structure plans, traffic signal plans, signing and pavement marking plans, maintenance and protection of traffic plans, lighting design and plans, constructability review, utility coordination, project specifications and engineering estimate (PS&E) package.
